I would agree that syn media may flow a tad bit more for any given loading and duration of use. A tad bit, not a lot.
There is one underlying questions here ....
Does the filter(s) of choice flow enough for your application and intended FCI??
I'd have to say that any filter, regardless of media, is going to flow WAY more than the pump is going to put out. You may get a slightly lower flow rate (I mean really low difference), perhaps due to a slightly higher dP (minimal difference, again), contrasting the cellulose to syn media choices. But those delta values are essentially worthless to anyone other than the anan-retentive BITOGer who cares more about spec sheet data than how the product actually works in his/her application. Most any filter will flow perhaps 2x the required volume for any given rpm, as a generalization. So if filter A will flow 4.1 gpm with syn media and filter B flows 4.0 gpm at some stated rpm, at temp 200F, but your engine is only putting out 2.3 gpm under those conditions, then why does it freakin' matter? Either filter is way more capable than the pump.
Too many of you go into battle with only half the information that it takes to make an intelligent decision.
You not only need to know what the filter is capable of doing, but also what the pump is capable of supplying.
Shame be upon you all; you should know better!
I've not seen any data that ever suggests the oil filters are anywhere near the restriction many want to believe. The syn vs cellulose media debate is no different than the syn vs. dino oil debate. People love to bench race what's in the box or bottle, and pay no attention to what the actual conditions present and how the results tell the tale of what success or failure looks like.
It is distinctly possible that a cellulose filter would eventually load up to near it's limit and see the dP escalate before syn media filter would do so. I would agree with that. But considering I've run OFCIs on "normal" filters out to 15k miles, and the subsequent UOAs, PCs and filter autopsy all show nothing at all was wrong, I've convinced myself the heretical attitude against normal products is way overblown. Normal products (cellulose filters and conventional oils) have WAY, WAY more capacity to perform than most folks think. I routinely run my OFCIs out to 2x and 3x of the OEM stated limits, and yet all the data shows no issues whatsoever.
Will a syn media filter flow a tad more? Yes.
Will it make a difference in your wear control for a "normal" application? No way in Hades.
